Answer:
267.14 iron oxide.
Explanation:
Given that
We know that molecular mass of iron-oxide = 160 g/mole.
We know that molecular mass of iron = 56 g/mole.
From the above reaction we can say that
1 mole of iron -oxide produce 2 mole of iron
160 gm of iron oxide produce 112 gm of iron
So
1 gm of iron required of iron oxide
Therefore
187 gm of iron required of iron oxide.
Therefore 187 gm of iron required 267.14 iron oxide.

Explanation:
An endothermic reaction is one that requires energy in the form of heat, which you observe from the outside as the chemical getting cold (like in a cold pack). An exothermic reaction is the opposite, generating heat on its own through the reaction (like in a hot pack).
